BACKGROUND Several studies have compared the treatment effects of coronary stenting and coronary-artery bypass grafting (CABG). However, there are limited data regarding the long-term outcomes of these two interventions for patients with unprotected left main coronary artery disease. METHODS We evaluated 1102 patients with unprotected left main coronary artery disease who underwent stent impl...
Objective—To investigate whether coronary stenting limits myocardial injury and preserves left ventricular function. Design and setting—Prospective multicentre case–control study of primary percutaneous transluminal coronary angioplasty (PTCA) with and without stenting, performed in seven cardiovascular centres. Subjects and methods—45 consecutive patients with acute myocardial infarction who w...
INTRODUCTION AND OBJECTIVES Direct coronary stenting yields immediate long-term clinical results similar to those obtained with balloon predilation, with the advantage of lower costs and procedural times. Until now, direct stenting has been attempted only for selected lesions, so that the potential scope of its use in everyday practice remains unknown. The DISCO 2 trial was designed to identify...
congenital anomalies of coronary arteries, albeit rare, may be significant contributors to angina pectoris, hemodynamic abnormalities, and sudden cardiac death. a 47-year-old man referred to us with atypical chest pain. electrocardiography demonstrated no significant ischemic changes, but cardiac troponin i test was positive. the patient underwent coronary angiography, which revealed a single c...
Cardiac transplantation is a well defined therapy for end stage heart failure. After the first year of transplantation, allograft coronary artery disease (ACAD) is the second main cause of death. The ACAD is defined as a diffuse process affecting the entire length of epicardial vessels. Once ACAD has been established, treatments such as coronary angioplasty, coronary stenting, and coronary bypa...
Over the last three decades, percutaneous coronary intervention (PCI) technology has revolutionized the field of cardiology. PCI began in the form of balloon angioplasty, and was followed by coronary stenting. In-Stent restenosis is the main limitation of coronary stenting, and has been delayed to some extent by the development of drug eluting stents. Coronary angioplasty with stenting is curre...
On the basis of clinical trials comparing coronary-artery bypass grafting (CABG) with medical therapy, current guideline recommend CABG as the treatment of choice for patients with asymptomatic ischemia, stable angina, or unstable angina/non-ST elevation myocardial infarction who have left main coronary artery disease. Percutaneous coronary intervention can be selectively performed in patients ...
AIMS The management of ostial lesions is one of the challenges of percutaneous coronary intervention (PCI) in recent medicine. Although stent implantation has increased the accuracy of the results and improved long-term outcomes, in-stent restenosis (ISR) occurs more frequency following the treatment of ostial lesions than the treatment of non-ostial lesions. When additional stenting is not des...
In addition to optimal medical therapy, some patients with coronary artery disease also require intervention on symptomatic and/or prognostic grounds. The debate over the relative efficacies of coronary artery bypass grafting (CABG) and stenting has recently been settled by the publication of the five-year outcomes of the SYNTAX and FREEDOM (in patients with diabetes) trials accompanied by supp...
Situs inversus with dextrocardia is a rare congenital anomaly. There are limited published case reports of successful percutaneous coronary intervention (PCI) in these patients who have atherosclerotic coronary artery disease, especially when presenting with acute myocardial infarction. PCI is technically difficult because of mirror image dextrocardia. We hereby describe a 48-yr-old female, who...
